IMPROVEMENT IN SEQTIONAL CHIMNEYS.

Specification forming part of Letters Patent No. 197,096, dated November13, 1877 application filed October 4, 1877.

To all whom it may concern:

Be it known that I, LEONARD E. CLAW- SON, of the city and county of SanFrancisco, and State of California, have invented Improvements inSectional Chimneys; and I do hereby declare the following to be afull,clear, and exact description thereof, reference being had to theaccompanying drawings.

My invention relates, first, to a novel band for binding together andcovering the joints of the sections used in the construction ofsectional chimneys; secondly, to an improved arrangement for bracing thechimney, all as hereinafter more fully described.

Referring to the accompanying drawings, Figure 1 is a view, inelevation, of my device. Fig. 2 is a vertical section.

Let A B represent two tubular sections or pipes, such as are used in theconstruction of sectional chimneys. To connect these joints or sectionstogether I reduce one end of each section, and form a correspondingchamber at the opposite end, so that the reduced end of one section willfit into the chamber end of the other.

A short distance below the shoulder, at the reduced end of each joint, Iform a projecting ledge or flange, D, for my improved band to rest upon.This band consists of a main central ring, F, which is largergindiameter than the pipes over which it fits. To the lower end of thisband I attach a smaller band, G, which is quite narrow, and which willfit snugly upon the chimney-section. The upper edge of this lower bandor collar is united with the lower end of the band F, so as to make aperfectlytight connection. Above the band F, I secure another collar orring, H, which also fits snugly over the pipe, and its lower edgeisconnected at intervals with the upper end of the band F, so as toleave slots or openings I between the connections.

When the recessed end of one pipe has been fitted over the smallend ofthe pipe below, I

place this band overthe upper end of the pipe, so that the lower ring orcollar G will .rest upon the projecting ledge or flange D. When therecessed end of the section above is placed over the small end of thissection, it will pass inside of the upper ring or collar, H,

so that the band willentirely surround the joints.

The large band F, standing away from the pipe, will form a circularchamber around the joint, which chamber I fill with cement or plaster,through the openings I. This forms a perfectly-tight joint-band, andalso binds the two ends of the sections together.

The band is easily applied, and can be cheaply made.

At the base of the chimney I place a similar ring, in which the lowersection rests.

The bottom of this band is made fiat, so as to rest upon the top of thefire-place or other support.

To brace the chimney, I connect each band F, either with the studding ofthe house or with a studding specially applied for that purpose, bymeans of the connection L.

When the special studding is employed, I construct a pan or socket, M,in which the foot of the studding will rest, and this pan or socket Iconnect with the lower joint-band, as represented. This enables me tosteady the chimney and keep the sections in place, so that they cannotbecome displaced unless the house settles.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A joint-band for sectional chimneys, consisting of rings or collars GH, and intermediate band F of larger diameter, arranged to form achamber or recess around the joint, which can be filled with cement orplaster through openings I, substantially as above specified.

2. The pan or socket M, connected with the lower joint-band, incombination with the connections L, for bracing and steadying thechimney from the studding of the house, or from a specially-erectedstudding, substantially as above specified.

In witness whereof I have hereunto set my hand and seal.

LEONARD E. CLAWSON.
